Ah, the props are spinning and then stopping before takeoff - I thought you were saying that the Breeze is spinning when airborne, i.e. rotating around its vertical axis.
So, the calibration idea is off the table with that. But still, nothing to do with the Bluetooth controller either.
Can you tell us exactly step by step how you get to the moment when the motors stop again? This happens after/during the normal start sequence? And there is no error message on the screen? What do the icons on the top border of the screen look like? Do the motors sound different to what it was like before? Has there been a crash?
